LEWIS WILKINSON, OF CHICAGO, ILLINOIS; FREDERICK M. STEELE, ADMIN- ISTRATOR OF SAID LEW'IS WILKINSON, DECEASED.

TURN-BUCKLE.

SPECIFICATION forming part of Letters Patent No. 328,443, dated October 13, 1885.

Application filed October 25, 1884. Serial No. 146,505. (No model.)

1'0 all whom it may concern:

Be it known that I, LEwIs WILKINSON, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in 'IurnrBuckles, of which the following is a specification, to wit:

This invention relates to turn-buckles; and it consists in certa n peculiarities of the construction of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which- Figure l is a side elevation, and Fig. 2 a central vertical section of my invention.

A represents the heads or ends of my turnbuckle, into which are screwed the rods a a, which are to be tightened by eithera right or left hand screw-thread, as required, and B B are the bars forming the sides of the. buckle and connecting the heads together. These bars B have commonly been welded to the heads or end bars, and as this welding'is often imperfect, and the imperfection not detected till the device is put in use, breakage often occurs when a s rain is put upon them, and

there is no way of ascertaining the strength 1 till an actual test is made. To obviate this, I provide the bars B with rigbtand left screwthreads I), which enter similiarly-threaded holes I) in the heads, and form a tirm connection, the strength of which can always be calculated without difficulty before the article is taken from the shop.

WVhile I design to make these turn-buckles of any size required they are especially valuable for large and heavy work where the most annoyance has been felt at the large number of breakages in using the welded ones.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A turn-buckle having its side bars secured in the ends or heads by right and left screwthreads, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

LEWIS WILKINSON.
